l This invention relates to a novel use with conventional spinning or winding machines for causing a preliminary Winding or bunch toibe appliedto a bobbin or quillto insure that mechanisin'for which will thereafter release the buncher' disk to render it inoperative and so. that the machine can thereafter function a conventional manner for. laying a full supply of yarn on the'bobbin.

More'particularly, it is an'aim of the present invention to ''provide such a construction of buncher guide, constitutingithe present invention, which is actuated by engagement withthe conventional buncherdisk of the machine and which includes a threaded member engaged. by the buncher disk and caused, by'traction'al engagement therewith to revolve with the buncher disk until'said disk rides out of engagement with the launcher "guide and at which'tim'e the bunch will have been applied to the bobbins.

IA further object of the invention is tof'provide such" an attachment having an adjustable weighted means for causing the attachment I to resume its initial positioniwhen the machine is reset for laying a bunch on another set of bobbins and to insure theilaying' ofa bunch of uniform size on successive sets of bobbins.

sun a furtheriobje'ct er the invention is to pro vide a buncher' guide attachment for spinning and winding machine's of extremely simple con-' struction which is capable of being economically. manufactured and sold and which may be very quickly and easily applied to spinning machines already in existence to' afford; a means whereby such-machines will function to ac'curately apply bunches'of various'sizes to bobbins or quills and which'after being set will apply bunches of uniform sizes to successive sets-of bobbins untilresetting of the buncher guide.

Numerous other objects and advantages of the invention will hereinafter become more fully apparent "from" the following'de scription of the drawings; illustrating'a presently preferred"em-" bodiment thereof, and: wherein:

Figure is an elevational view of a bobbin or quill sh'owing the original build of yarn on the bobbin produced by the normal operation of the machine and after the buncher guide attachment has completed its operation, and v v Figure 8 is a view similar to Figure 7 showing the bunch applied to the bobbin or quill by the operation of the buncher guide in combination withthebuncher disk of the spinning machine. J 7 I Referring more, specifically to the drawings, for the purpose of illustrating the application and operation of the buncherguide attachment, comprising the invention and which is designated generally I0, a portion of a conventional spinning machine has been illustrated in Figure I and is designed generally II. and includes; such parts as f unction in combination with the attachment ill or as are affected by the operation of said attachment. One side wall l2 of the spinning machine ll is shown and itwill be understood thatsaid machine likewise includes a correspondingopposite side wall, not shown, which side walls provide asupport for the upperand lower rails I3 Ian d M. The upper rail l3.provides the conventional bobbin or quillsupport on which a plurality of bobbins [-5 are rotatably supported in upright positions foi receiving the' strands of yarn 16 from a suitable supply source 11 and which are adapted to be wound thereon in a conventional manner. The bobbins l5 are revolved in aconventional manner by a driven belt 'neans'18". The bobbins or quills I5 extend upwardly through openings in a conventional ring rail"!!! which is supported by'a plurality of push rods which extend reciprocally through the members l3 and I4, butone of which is shown at 20 v in Figure 1. Each of'the push rodsI-Zfl'is profixed to a shaft 24 which shaft is suitably jourand hasan upwardly extending arm" 25 which is naled inbearings, not'shown,"of the machine ll fixed thereto and h'a's'a segment portion 26 at its upper end to which is "connectedone end of a flexible member 21. "A weight 28 is likewise fixed "to and-projects fromthesha ft fl in a direc-' tion opposite to the lever 23' "for urging said shaft 24 to rock in a direction for swinging the lever 23 upwardly to exert an upward thrust on the push rod-2'0 for elevating the rails '19. The flexible member 21: extends substantially horizontally from the segment 26 and has its intermediate portion trained over a pulley 29 which projects,

inwardly from the wall l2 and extends downwardly from said pulley and is fastened at its opposite end to the builder arm 30 which is arm 30 which have been illustrated in Figure 1'" and which function in a conventional manner will not be described except for the roller'3l which is supported on a bracket 32, as illustrated v in Figures 1, 2 and 3. A driven shaft 33, having a portion journaled in the wall [2, extends transversely across the builder arm 30 and has a main builder cam34 fixed thereto and disposed'over the roller 3! for engagement therewith when the builder arm' 331s in its position of Figure 3 and so that astheroller 3| rides over the high and low portions of the periphery of the cam 34 saidbuilder arm 33 will be rocked vertically for exert ing a, pull on 'the flexible member 2? as the builder arm 3liswings downwardly to rock the lever 23, shaft 24, arm and weight 28 in a counterclockwise direction as seen in Figure l to permit the-rail i9 and its supporting rods '20 to move-downwardly relatively to the bobbins l5; whereas, when the roller 3| moves into engagement with a low point cam 34 the arm is swung upwardly bytheweight 28 whichcauses the shaft, arm 25- and lever 23 to swing clockwiseand so that the roller 22'will exert a'thrust on the push rod 20 for displacing the rail' l9 upwardly relatively to the bobbins 15. The driven shaft '33 also has a buncher disk 35 adjustably fixed thereto by means of asetscrew 36 which extends radially through thehub of the disk 35' and which 'diskis disposed over the 'buncher guide attachment ID. The buncher disk 35 is provided with scalloped periphery 31 for a'purpose which will hereinafter become apparent.

The parts H to 31-, previously described and illus trated in Figure'l form no part of the present invention but have merely been illustrated and described briefly to afford a better understanding of the buncher guide attachment H) which comprises the invention and which" functions in com-' bination with the launcher disk 35 to initially cause the machine I -I to apply a bunch of a predetermined size to a selected part of the bobbins orquills-l5.

"Said buncher guide attachment In, as best illustrated in FiguresZ' to 6; includes a, supporting bracket 3&whichis'g'enerally U-shapedand has a shorter upstand'ingleg 39 which is fastened to the builder arm 30 by'fastenings 40on the side thereof opposite the side from which the bracket 32extends and which fastenings 4G- demountably support the builder guide It on the spinning machined-Ir The other, longer "upstanding leg 4I' of v the bracket 33 has a longitudinally or vertically elongated opening 4=2formed therein for receiving. the restricted threaded shank. 43' which projects.

from one end of a shaft 44 through a portion of the opening, 42' and to which a nut 45 is applied toi'combine with the annular shoulder formed around the end of the shaft. 44 from whichthe threadedstem 43' projects for'adjustably clampingsaid shaft 44on the bracket 38 so that said shaft may be-mounted at various levels. relatively to the builder .arm130, for a purpose whichwill herein{ after becomel apparent. V

elongated guide member 46 is rotatably supported on the shaft 44 adjacent the bracket 3 3l. iand the end-thereof located nearest the bracket 38' is provided with a relatively deep thread 41. The opposite, unthre'aded end 48 of the guide member 46 is provided with an internal recess 49 for containing a segment-shaped weight 50 having an outwardly opening threaded recess 5lintermediate of its ends for receiving the threaded'shank of a setscrew 52 which extends through a portion of a circumferentially elongated opening 53 formed in the cylindrical portion 48 The setscrew 52 is tightened for clamping the weight to the member 46 and it will be readily apparent that said setscrew can be loosened and adjusted circumferentially of the member 46 for adjustably positioning the weight 50 circumferentially of the "guide member 46; for a. purpose which will hereinafter become apparent. v l v\ A spring stop 54 is adjustably positioned'oii the shaft 44 adjacent its opposite endand re. mote to the bracket 38 by va setscrew 55 and said spring stop 54 is provided with openings 56 in an annular flange portion thereof which. are sized to reciprocally receive the threaded ends; are; pair of'rods '51 having corresponding ends ex tending from the stop 54 toward the guide mem ber 46' and terminating in restricted threaded' terminals 58, as seen in Figure l, which engage in threaded recesses 59 of a disk 60"1which" is slidablymounted on the shaft 4'4an'o1 which bears against the annular free" end of the guide portion 48.. Each rod 5 1."carries an expansion coiled spring 5| bearing at its ends against a'd-, jacent sides of the spring stop'54 and disk fifl'fo'rl yieldabl urging said, diskrifillftoward the bracket 38' to normally retain the guide member 45 against the outer leg 4| of the bracket'38. The threaded opposite, first mentioned ends of-the IOds 51f are preferably each provided with a nut 62. which nuts engage the outer-side of'thejspring stop 54 and are adjustable for varying the extent that the springs Bl' can move the" disk 60 toward the bracket 38. V i

To apply a bunch 63, as illustrated in Figure 8; to a plurality of bobbins or quills [5 which are mounted in the V spinning m chine] H," [the buncher disk 35 isinitiallj set by means time setscrew 36 in a' desired position "on the driven shaft 33 and the b'uncher guidelo' vertically adjusted to a desiredl'p'o'sition" in the slot 42,}as previously described. The builder arm 30'" can then be manually swung downwardly to position the guide member 46 beneath the lowermost point of the buncher disk 35v and the spring 6.1

will th en move the buncher guide .45 to the le'ft' and into its position of Figures) and 4 against the bracketportiori. 4|; Thear m 30 ,is then/released and swung fupwardlyi'byQ the weight'28 so that a portion of the flu-ted edge 37- of the dis k 35 willreng'age in the spiral. groove of the thread.

41; as illustrated in Figure 4, for holding thearm 30 sufficiently depressed; so that the roller 3| will not contact any part of the cam 34. As thedisk end; of the member 46due to the fact that said-v member 46; willbe displaced from left to right of Figures 2, 3, and i as; it is revolved bythe'enegagement of the buncher disk: 35 with its thread 41 and against the action of the springs 6| which will be compressedtopermit the member- 46-and the spring ,i ollower-disk W to move from left to right on the shaft 40. so that-the guidemember 46 not only revolves but reciprocates relatively to the shaft 44 during this rotary movement of the buncher 35 and buncher guide member 46. The valleys between the points of the scolloped edge 31 will produce a slight vertical rocking movement of the builder arm which will be transmitted as previously described to the rail l9 to cause the bunch 63 to be applied over a relatively restricted area lengthwise of the bobbins or quills l5. When the scolloped edge 31 moves out of engagement with the left-hand end of the thread 41 it will assume the position of Figure 3 and so that the weight 28 can swing the builder arm 30 upwardly to displace the roller 3| upwardly and into engagement with the cam 34 which will thereafter function to rock the roller arm 30 vertically through a greater arc, as previously described, for laying the regular service winds. It will be readily apparent that after the bobbins or quills have been filled and removed and replaced by another set of bobbins or quills, that the aforedescribed operation can be repeated for laying the yarn on the-new set of bobbins or quills and that by again moving the builder arm 30 downwardly the spring 6| will return the bunch guide member 46 to its initial position as illustrated in Figure 4 to function with the buncher disk 35 to apply the bunch initiall to the new sets of bobbins. It will also be readily apparent that by vertically adjusting the buncher member 46 relatively to the bracket 38 by means of the slot 42, that the location of the bunch on the bobbins or quills can be varied longitudinally of the bobbins.

To insure the application of bunches of uniform sizes to successive sets of bobbins or quills the adjustable weight 50 is provided and it will be readily obvious that by circumferentially adjusting the weight 50 by means of the setscrew 52 and slot 53, that the location of the center of said weight with respect to the left-hand end of the spiral thread groove 41 off of which the scolloped edge 31 moves, can be varied. Since this together with the location of the buncher disk 35 on the shaft 33 determined the size of the bunch 63, to produce bunches of uniform size on successive groups of bobbins makes it necessary that a corresponding portion of the groove of the thread 41 be positioned each time to initially receive the scolloped edge 31 to commence the forming of the bunches and which is accomplished by the weight 50 since when the edge 31 is out of engagement with the thread 41, said weight will cause the guide member 46 to turn sufiiciently to permit the weight to assume a lowermost position as illustrated in Figures 5 and 6. Assuming that the left-hand end of the thread 41, representing the point on the guide 46 where the scolloped edge 31 moves out of engagement with the bunch guide member 46, is located in longitudinal alignment with the left-hand end of the slot 53, as seen in Figures 5 and 6, it will be readily apparent that by displacing the weight 50 in a clockwise direction as seen in Figures 5 and 6, will result in the disk 35 traveling a further distance in the thread groove with a predetermined setting on the shaft 33 and accordingly applying a greater amount of yarn to the bunch.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.

I claim as my invention:

1. A bunch builder attachment for use with winding and spinning machines comprising a buncher disk adapted to be adjustably secured to a driven cam shaft of a spinning or winding machine for rotation therewith, a buncher guide operating with said buncher disk for applying bunches to spindles or quills of the machine including a supporting bracket adapted to be demountably fastened to a swingably mounted builder arm of the machine, a buncher guide shaft secured to said bracket and projecting therefrom in substantially a horizontal plane, a buncher guide member rotatably and slidably mounted on said buncher guide shaft having a threaded peripheral portion receiving the periphery of the buncher disk, and spring means supported by the buncher guide shaft and spring biasing the buncher guide member toward the bracket, said buncher guide member being rotated by engagement with the rotating buncher disk and having the thread thereof pitched to cause the buncher guide member to be displaced away from the bracket to release the buncher disk from an end of the threaded portion thereof for movement into the space between the bracket and buncher guide member, said buncher guide member when in engagement with the buncher disk functioning to retain the builder arm in a depressed position and in an inoperative relationship relatively to a main builder cam of the machine which is carried by and rotatable with said driven cam shaft, said .spring means including a spring stop mounted for longitudinal sliding movement on the buncher guide shaft adjacent the end thereof disposed remote to the supporting bracket, a setscrew carried by the spring stop and engaging the buncher guide shaft to adjustably secure the spring stop to said shaft for varying the tension of the spring means on the buncher guide member.

2. A bunch building attachment as in claim 1, said buncher guide member including a chamber disposed around a portion of the buncher guide shaft, a weight defining a segment of a ring loosely disposed in said chamber and movable therein in an arcuate path around the buncher guide shaft, said buncher guide member including a cylindrical wall portion surrounding said chamber and provided with a circumferentially extending slot, and a headed clamp screw having a threaded shank extending loosely inwardly through said slot and threadedly engaging said weight, said clamping screw permitting the weight to be circumferentially adjusted relatively to the buncher guide member when loose and being tightened for adjustably clamping the weight to the buncher guide member, said weight functioning to cause the ends of the thread of the buncher guide member to assume the same circumferential positions each time that the buncher guide member is returned by the spring means into a position beneath the buncher disk.
